The use and operation of my invention are. as follows: My machine has have opposed dish-shaped crushinfr surfaces rotating equnllym the same tdirection at an angle with each other, and the material is fed into lthc central, space bet-Ween .them and carried hy `centrifugal force outwardly toward their more nearly approaching surfaces. Since these surfaces are at anl an le with each other, they ap roach and rece e during their rotation, crus ing the' material as they al proach each other, and allowing it to travel farther out as they recede from one Smother, until it is fine enough tobe thrownont by ccn'trifugl force from between the crushing members. These members are mounted each upon a alla@ supported one within the other ,han a, hall and socket joint. The exterior gsiaft is mounted in any suitable bearings und a free circulationpoflubricatin^"ol 1s Aescape of oil only at tho ends and by protccb ing the ends. ci the bearing b groove@ sleeves about collars rotation' with the shaft. "lhc oil is forced into the bearings hy any suitable means, paes out and is caughtup upon vanos. of the rotating collalgS and (limon into the grooves in the stationary .Slh passing back to the reservoiin The Water choline' system consists of a tank with connections leading thence to water cooling chambers wit-hin the'bearings,`ppes and rc turn pipes so that as the water heats it circulates and rises to the tank. 'llo overcome the tendency-of the two shafts to more with reference to each other lon itudinally and thus unseat their bull and soc et bearing, the inner shaft is provided with u sleeve which enga es the outer end of the outer' shaft so as, w rile permitting a swinging motion of the shafts withy reference. to each "other, to prevent their longitudinal motion. "This sleeve is carried in a. vertically adjustable bearing, thus permitting adjustment of the angnlarty of the crushing members. Ono crushing platev is held upon the crushing gnging a tapered surface upon the plate, the

`against relation by teeth engaging teeth upon a disk, which is held -by lu s cngagin a plurality of holes, and ma be isconnecte from the screw by a. smal er screw carried in the screw, and enga ing a lug on the disk. Thus Athe crushing p atea, w ich are the wearin parts, are removably held inposition. he crushing members are surrounded by a hood which catches the crushed mo.- tcrial as it is thrown out, but the high speed at which the material travels necessitates frequent renewal ofthe Surface upon which they mpnge. This is provided for byhaving a ring m the plane of discharge, which provided by using sleeve bearings, a owingolber by a centrally located screw, heldA having,l a curved cross section, the rollers -voV member by bolts having tapered heads enspun. of my invention.'
